|Keywords:||Aerodynamics;Turbulence;Isotropy subgroups;Fluid mechanics;Shear waves||Category:||Civil Engineering||Field:||Engineering and Technology||Issue Date:||2007||Publisher:||American Institute of Physics||Source:||Physics of Fluids, 2007, Volume 19, Issue 12, pages 128106||Abstract:||We apply inviscid rapid distortion theory to the generalized case of turbulent hyperbolic flow in a rotating frame and investigate the dependence of the evolution of the turbulent kinetic energy on the frame rotation rate. We derive an analytical two-dimensional solution which allows for an accurate approximation of the three-dimensional initially isotropic problem. From the analytical solutions we determine a new generalized stability criterion for the evolution of the turbulent kinetic energy in this class of flows||URI:||http://ktisis.cut.ac.cy/handle/10488/8743||ISSN:||1070-6631||DOI:||10.1063/1.2821911||Rights:||© 2007 American Institute of Physics||Type:||Article|
